Abstract :
The aim of this study was characterization of Biocomposite CoHA-Gelatin-PVA. CoHA (Calcite Omya Hydroxyapatite was obtained from local material by synthesizing local calcite, while gelatin and PVA was commercial from Merck. The composite was prepared by blending powder of CoHA, gelatin, and PVA with weight ratios of 1:1:0.15. This blended powder composite was then mixed with distilled water with various solid loading of 5, 15, and 25% w/v. Next, it was cooled at freezer prior freeze drying to build a porous block composite. Characterization was carried out by XRD, FTIR, and SEM. The results showed that the composite block has micropore size <;10 and macropore up to 300 μm. Results showed that the HA-gelatin-PVA can be synthesized into porous biocomposites, which has the potential for bone graft. The biocomposite has low cristallyne structure and there is a complex network structure of HA-gelatin-PVA. Biocomposites have a macropore up to 300 μm and micropore up to <;10 μm.
